Viabilidade econômica da produção tecnificada de tilápias na região da Grande Dourados, MS

Abstract

The study of the economic feasibility of enterprises in the region is a prerequisite for strengthening the growing production chain. Analyzing different sales price scenarios in the studied region opens dialogues for sector development and understanding the activity's bottlenecks in the area. This research aimed to evaluate the implementation of technified tilapia farms in different water surface areas (5 ha, 10 ha, and 20 ha) in the southern region of Mato Grosso do Sul, in the Midwest of Brazil. The system adopted for evaluation is the semi-intensive system in excavated earthen ponds with monk drainage. Stocking is done with juveniles of 40g at an initial density of 6 fish per square meter. A cultivation time of 210 days, 95% survival rate, final weight of 840g, and feed conversion ratio of 1.47:1 were considered. The productivity per hectare per cycle considered was 48 tons per hectare per cycle and 73 tons per hectare per year. The cash flow was projected over a 10-year horizon. The following indicators were calculated: net present value (VPL), internal rate of return (TIR), modified internal rate of return (without reinvestment), and simple payback. The discount rate used was the cost of equity [ke]. The sales market considered was the sale to the processing industry. The results indicate that for this market, the area size influences the indicators, and therefore, farms larger than 10ha are suggested as they have greater resilience to price fluctuations paid by the industry.
